John Hayes:
Have you searched for mirror locks? I once bought mirror locks for a C14 XLT that used the shipping screw holes for a locking mechanism.

Thanks Andrea and John - The telescope is remotely installed so mods are a bit tricky given the need for equipment and stuff. If i can get my hands on some damaged or 2nd hand C11 tho i could do it at home and then simply swap the back plate with the modded one. I asked Celestron and you are right, those parts arent available as spare, unfortunately.
John, i read about those mirror locks for C14 some time ago - those were a great option but unfortunately, they were unavailable for C11 scopes at that time. Now i cannot find the ones for the C14 either, i think they arent being produced anymore
